Once you have subtracted both your "x" and "y" values, you can divide the differences: (2) / (2) = 1 so the average rate of change is 1. You can convert the average rate of change to a percent by multiplying your final result by 100 which can tell you the average percent of change. Additionally, the rate of change can ...Rate of change is calculated by subtracting the present value of a variable from the old value, dividing it by the old value, and multiplying the result by 100. For example, in the case of securities, subtract the current price of a security from its price a few days ago (old price) and then divide the difference by the old price. Then, to get ...To understand the difference between the average rate of change and instantaneous rate of change, consider a car driving 5 miles. The journey takes the car 12 minutes. This means …

Explanation: . Since the question is asking for the rate of change in terms of the perimeter, write the formula for the perimeter of the square and differentiate it with the respect to time. 4. The Derivative as an Instantaneous Rate of Change. The derivative tells us the rate of change of one quantity compared to another at a particular instant or point (so we call it "instantaneous rate of change"). This concept has many applications in electricity, dynamics, economics, fluid flow, population modelling, queuing theory and so on.The instantaneous rate of change at a point is equal to the derivative function evaluated at that point. Further, the average and instantaneous rate of change at a specific point can map in the graph as the tangent slope line, which shows like a curve slope.
